Vice President Vance [Naval Academy Commencement Address]: I actually think the most significant part of that trip [President Trump, Middle-East] is that it signified the end of a decades-long approach in foreign policy, that I think was a break from the precedent set by our founding fathers. We had a long experiment in our foreign policy that traded national defense, and maintenance of our alliances, for nation building and meddling in foreign countries affairs. Even when those foreign countries had very little to do with core American interests. What we are seeing from President Trump is a generational shift in policy. With profound implications for the job that each and every one of you will be asked to do.
